The spring constant is then given by Δ F = k Δ x because F 1 = k x 1 and F 2 = k x 2. Share. Cite. butterfly garden landscaping ideas

WebHooke experimented with springs because he thought it must be possible to design a clock or stopwatch which used a circular spring in place of a pendulum for regular time … WebThis follows Hooke’s law which states that the extension of an elastic object (like a spring) is. to the force added. When the dependent variable is directly proportional to the independent ... WebWithin certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke's law and commonly written: \boxed {F=-kx} F = −kx.
